To go beyond the limitations of other existing LS blocks, the new RHS® LS Aluminum Race Block is available in both standard deck and tall deck height configurations. Additionally, this innovative block features a raised cam centerline and outboard priority main oiling to allow rod clearance for a 4.600″ stroke and to minimize windage in the crankcase. For quality control assurance, RHS® conducts a CT scan (similar to a medical CAT scan) on each block to ensure maximum casting precision and consistency.

When you combine unmatched finishing quality with added clearance for increased stroke applications, precision computer-aided design and extra surface material to allow custom machining, you get the new benchmark for LS horsepower, torque and durability.
